'mac.l' Assembler Operands Mismatch on 5282

[Sam Skuce]

I have some code that compiled with no errors under a 3.3.2 version of
m68k-elf-gcc, that gives me the error "operands mismatch -- statement
`mac.l %d0,%d7' ignored" with m68k-elf-gcc-4.2.0.  I have tried
compiling it with:

$ m68k-elf-gcc-4.2.0 -c -g -mcpu=5282 -Wall -O3 -fno-builtin
operandmismatch.S -Wa,-acdhlns=../obj/operandmismatch.lst -o
../obj/operandmismatch.o

And 

$ m68k-elf-gcc-4.2.0 -c -g -m528x -Wall -O3 -fno-builtin
operandmismatch.S -Wa,-acdhlns=../obj/operandmismatch.lst -o
../obj/operandmismatch.o

(difference is -m528x versus -mcpu=5282)

Here is a sample file I used to duplicate the problem, all the mac.l
instructions generate the error:

/* BEGIN SAMPLE FILE */

	.global function
	.global _function

	.text
	.align	4
function:
_function:


    move.l  #0, %acc 
                            
    move.l  (%a2)+, %d7     
    mac.l   %d0, %d7        

    move.l  (%a2)+, %d7     
    mac.l   %d1, %d7        

    move.l  (%a2)+, %d7     
    mac.l   %d2, %d7       

    move.l  (%a2)+, %d7     
    mac.l   %d3, %d7

    move.l  (%a2)+, %d7     
    mac.l   %d4, %d7

    move.l  (%a2)+, %d7     
    mac.l   %d5, %d7

    move.l  %acc, %d7       
    move.l  %d7, (%a0)+
    

	rts



    .end

/* END SAMPLE FILE */

What do I need to change to make this work with the new gcc version?

Thanks!
